Scripted by Diablo Cody, who won an Oscar for Juno, this is the week's only vampire movie. A semi-serious, extremely bloody affair, it's set in the town of Devil's Kettle, where a band of Goths sacrifice the high-school beauty (Megan Fox) to Satan to take their band into the big time. Unfortunately she's not a virgin and thus remains alive to become an insatiable flesh-eating bloodsucker, terrorising the neighbourhood. It's narrated from the local correction centre by her incarcerated best friend (Amanda Seyfried, currently to be seen 24-hours-a-day on cable TV in Mamma Mia!) who declares the film's theme in her opening sentence: "Hell is a teenage girl." The film is not without merit and has more corpses and red corpuscles than the anaemic Twilight series of vampire flicks.
